Only one verification test!? and this test already has the vector sorted.

li look up the options of the sort command

Needs (much) more tests in the Test Suite!! It would also be a good idea to include a randomly generated vector in the tests; for this random input, testing of the correct function output should be hard-coded as: assert(y(1)>=y(2)); assert(y(2)>=y(3)); ... ; assert(y(end-1)>=y(end)); [It's not the most efficient check, but anything else will risk giving away clues on possible solution codes.]

Every time again, it's pretty amazing, to see what powerfull little functions are implemented in Matlab!

You can do this with one function call. See the mode flag in sort().
